BACKGROUND:China has the most patients with diabetes mellitus (DM) in the world and, annually, approximately 1 million Chinese become diabetic. We investigated both clinical and economic outcomes in a large Chinese cohort of diabetic patients undergoing coronary artery bypass graft surgery (CABG).METHODS:All 9,240 consecutive patients who underwent isolated, primary, elective CABG between January 1999 and December 2008 were included and analyzed for long-term major adverse cardiovascular and cerebrovascular events and economic outcomes up to 2 years after the procedure. The DM patients were divided into DM subgroups controlled by diet (n = 375), medication (n = 1,826) or insulin (n = 481).RESULTS:During the study period, the proportion of patients undergoing CABG who have DM increased from 20.1% to 31.8% in China. None of the DM subgroups was independently associated with in-hospital death, but DM was an independent predictor for long-term major adverse cardiovascular and cerebrovascular events (hazard ratio 1.29, 95% confidence interval: 1.14 to 1.46). Medically controlled DM and insulin-dependent DM, but not diet-controlled DM were independent predictors of long-term outcomes after CABG. Cost for initial hospitalization was higher for DM patients (76,782 Ren Min Bi [RMB] versus 65,521 RMB, respectively; p < 0.001). At 2 years after CABG, costs for DM patients were 11,261 RMB (approximately US $1,623) higher than for non-DM patients (p < 0.001).CONCLUSIONS:CABG for patients with DM was significantly more expensive and was associated with worse long-term outcomes compared with non-DM patients. The rising incidence of DM, combined with the significant incremental costs represents significant clinical, economic, and social challenges for the Chinese healthcare system.

OBJECTIVE:To investigate the association between physical activity (PA) and the incidence of metabolic syndrome (MS) in Chinese adults.METHODS:Data on PA and other variables were obtained at the baseline examination of China Multi-center study of Cardiovascular Epidemiology in 1998 and of International Collaborative study of Cardiovascular Disease in Asia(InterASIA) during 2000 - 2001. Follow-up study was conducted in 2007 - 2008. A total of 11 512 Chinese adults aged 35 - 74 years (5563 men and 5949 women) were included in the final data analysis. Information on demographics, PA, smoking and alcohol consumption were obtained and components of MS were examined. Participants were divided into four groups according to quartile of total metabolic equivalent (MET) values per day. In addition, subjects were grouped into the following categories according to occupational PA: inactive, light, moderate and vigorous. Binary logistic model was used to examine the association between PA and the incidence of MS.RESULTS:A total of 2527 cases with MS were documented during an average following up of 8.1 years. The annual incidence rate of MS was 2.71% (2527/93 178.68). After multivariate logistic regression analysis, compared with participants with total PA volume < 32.0 MET×h×d(-1) (annual incidence rate was 3.19% (697/21 830.74)), the RR (95%CI) value of participants with total PA volume during 32.00 - 37.85, 37.86 - 52.29, and ≥ 52.30 MET×h×d(-1) was 1.05(0.92 - 1.19), 0.98(0.86 - 1.12), and 0.68(0.59 - 0.80), respectively (χ(2)trend = 34.23, P < 0.05), with corresponding annual incidence rates of 2.82% (690/24 504.25), 2.73% (661/24 179.36) and 2.11% (479/22 664.33). In addition, compared to inactive occupational PA (annual incidence rate was 2.76% (402/14 588.33)), the corresponding RR (95%CI) value was 0.80 (0.69 - 0.92), 0.70 (0.59 - 0.82), and 0.54 (0.45 - 0.65) (χ(2)trend = 42.34, P < 0.05), and the annual incidence rates were 2.86% (648/22 663.41), 2.40% (455/18 956.14) and 1.89% (344/18 173.86) in participants with light, moderate and vigorous occupational PA, respectively.CONCLUSION:Both increased total PA volume and occupational PA intensity are significantly associated with decreased risk of incidence of MS.
